A hire purchase (HP)[1] or known as installment plan in the United States is an arrangement whereby a customer agrees to a contract to acquire an asset by paying an initial installment (e.g. 40% of the total) and repays the balance of the price of the asset plus interest over a period of time. Other analogous practices are described as closed-end leasing or rent to own.

The hire purchase agreement was developed in the United Kingdom in the 19th century to allow customers with a cash shortage to make an expensive purchase they otherwise would have to delay or forgo. For example, in cases where a buyer cannot afford to pay the asked price for an item of property as a lump sum but can afford to pay a percentage as a deposit, a hire-purchase contract allows the buyer to hire the goods for a monthly rent. When a sum equal to the original full price plus interest has been paid in equal installments, the buyer may then exercise an option to buy the goods at a predetermined price (usually a nominal sum) or return the goods to the owner.

If the buyer defaults in paying the installments, the owner may repossess the goods, a vendor protection not available with unsecured-consumer-credit systems. HP is frequently advantageous to consumers because it spreads the cost of expensive items over an extended time period. Business consumers may find the different balance sheet and taxation treatment of hire-purchased goods beneficial to their taxable income. The need for HP is reduced when consumers have collateral or other forms of credit readily available.

These contracts are most commonly used for items such as car and high value electrical goods where the purchasers are unable to pay for the goods directly.

If the seller has the resources and the legal right to sell the goods on credit (which usually depends on a licensing system in most countries), the seller and the owner will be the same person. But most sellers prefer to receive a cash payment immediately. To achieve this, the seller transfers ownership of the goods to a Finance Company, usually at a discounted price, and it is this company that hires and sells the goods to the buyer. This introduction of a third party complicates the transaction. Suppose that the seller makes false claims as to the quality and reliability of the goods that induce the buyer to "buy". In a conventional contract of sale, the seller will be liable to the buyer if these representations prove false. But, in this instance, the seller who makes the representation is not the owner who sells the goods to the buyer only after all the installments have been paid. To combat this, some jurisdictions, including Ireland, make the seller and the finance house jointly and severally liable to answer for breaches of the purchase contract.

To buy the goods at any time by giving notice to the owner and paying the balance of the HP price less a rebate (each jurisdiction has a different formula for calculating the amount of this rebate)

To return the goods to the owner—this is subject to the payment of a penalty to reflect the owner's loss of profit but subject to a maximum specified in each jurisdiction's law to strike a balance between the need for the buyer to minimize liability and the fact that the owner now has possession of an obsolescent asset of reduced value

With the consent of the owner, to assign both the benefit and the burden of the contract to a third person. The owner cannot unreasonably refuse consent where the nominated third party has good credit rating

Where the owner wrongfully repossesses the goods, either to recover the goods plus damages for loss of quiet possession or to damages representing the value of the goods lost.

to take reasonable care of the goods (if the hirer damages the goods by using them in a non-standard way, he or she must continue to pay the installments and, if appropriate, recompense the owner for any loss in asset value)

to inform the owner where the goods will be kept.

A hirer can sell the products if, and only if, he/she has purchased the goods finally or else not to any other third party.

it is pretty much similar to installment but the main difference is of ownership.

In Malaysia, the legislation governing hire purchase transactions is the Hire Purchase Act 1967, which came into force on 11 April 1968 after hire purchase became popular in the acquisition of expensive consumer goods such as cars, business equipment and industrial machinery. Purchasing cars is the most common type of hire purchase agreement in Malaysia and the repayment could take up to 9 years from the date of agreement been executed.
